Can supermodel Cheryl Tiegs outlast former Miss Universe Dayana Mendoza, who is four decades her junior? Who'll face the music first -- Clay Aiken or Debbie Gibson?

Those are just a few of the mouth-watering matchups expected on the upcoming season of "Celebrity Apprentice," premiering February 12 on NBC. PEOPLE confirmed several of the contestants back in October, but the cast was officially revealed Wednesday.

"I just think we have a major group of celebrities, and we have a very iconic group," says the show's host, Donald Trump. "This is the best cast we've ever had, the biggest cast, and it's going to be special."
